This item was purchased new at an electronics retailer. I have been using the SE215spe and kept this as a spare, but I started using other models in parallel, so I am selling off the spare. As it is a spare, there may be some scratches on the box. I have disposed of the receipt, so returns and exchanges are not possible, but the item is unopened, so please be aware of this.
